Reports states that employees of the pest control company secretly used undiluted pesticide by pouring it into bottled water containers to avoid government crackdowns. In some establishments, rodent poison was also used. According to China’s pesticide management regulations, the scope of use, application methods, and dosage specified on the label must be strictly followed when using pesticides.


An employee from the pest control company told media, “Even if someone offered me a free meal, I would never go to a restaurant that we have disinfected.”

The insecticide in question is highly toxic and mainly used for pest control in rural areas. Due to its high toxicity and cancer risk, its use is either restricted or prohibited in major cities and closed environments.


Investigations also revealed that employees sprayed the insecticide on restaurant tableware and chairs. One restaurant owner reported, “Because of the toxicity of the insecticide sprayed by the pest control company, all the seafood in the tank died.”



Local media reported that the market supervision and administration authorities are conducting a comprehensive investigation into the pest control company and related food service businesses.
